ABSTRACT

The preparation, composition, and method of use of an antibacterial formulation utilizing tannins, acceptable for agriculture and for use against bacterial and fungicidal diseases in plants. The composition is based on an organic matrix and may be balanced with dispersants, flocculants and humectants, and may be used against a wide range of agricultural bacterial diseases.

This application claims benefit to U.S. provisional application No. 62/722,782, filed Aug. 24, 2018; U.S. provisional application No. 62/723,168, filed Aug. 27, 2018; and U.S. provisional application No. 62/727,237, filed Sep. 5, 2018; the entire contents of each of which are hereby incorporated by reference in its entirety.

BACKGROUND

Bacteria are the most abundant microorganisms on our planet, and the prevention and control of bacteria and the diseases that they cause, particularly in the agricultural field, is of utmost importance as it directly impacts the food production needed for human sustenance. Some examples of this are mentioned below.

Erwinia amylovora has caused incalculable losses by destroying complete plantations of apples and pears in the countries in which these fruits trees are cultivated. For example, in the state of Chihuahua, Mexico alone, more than 50 thousand pear trees have died and more than a million trees of different apple varieties have been infected. This has caused both large and the abandonment of the cultivation of such fruits in producing regions of that state. Thus this has evolved from a phytosanitary problem for fruit producers into a serious social problem. Fruit growers are seriously worried about the symptoms of the disease, in that the infected trees seem as if they have been burned with a flamethrower, hence the name “fire blight.” This same situation has occurred in highly industrialized countries where these fruits are cultivated, such as, for example, the United States of America, England, France, and the countries of the former Soviet Union. After blossom season, bacteria splashed by moisture events such as drizzle, dew and wind can infect succulent shoots. Blight shoot or shoot blight appears one to several weeks after falling petals. Symptoms of the disease continue to progress through the spring and summer season in susceptible tissues, such as leaves and twigs.

Pierce's disease, caused by the bacteria Xylella fastidiosa, has strategic importance due to the amount of money that it cost when it attacks crops such as vine, olive, citrus, stone fruit trees, such as plum and peach, as well as almond trees. This causes a devastating effect as a result of the large surfaces it affects. It is also one of the most studied bacteria by scientists because of the bacteria's colonizing habit, in that it can survive in different varietal cuts that have been transported without strict sanitary control at borders. The disease has spread, and has been reported already in a good number of countries in Latin America, Europe, and Asia. This disease is considered to be a main factor limiting the expansion and success of affected cultivars.

In Central America and South America, thousands of African palm trees are dying because of an illness caused by a bacterium which has not been identified correctly. This has caused a need for alternatives for its control and for a product that can counteract the devastating effects of the plague. To do so, it is necessary to establish research protocols with the appropriate scientific rigor and for those protocols to be carried out with a large team of producers, and potentially governments, in order to establish the biological cycle of the pathogen and how to treat or prevent it.

In banana producing countries threatened by a terrible disease called “moko,” caused by a bacterium named Ralstonia solanacearum, there has been the loss and abandonment of complete crops, which are impossible to replant because the pathogen survives in the soil for years on the tissues of a sick plant. Farmers have to spend large sums of money to sterilize the soil by applying toxic materials, which causes negative effects on the beneficial flora and fauna in the area, thus altering the balance and delicate nutritional biogeochemical cycles present in that ecosystem.

Having the same importance are the bacteria that attack vegetables, grasses, members of the cruciferous family, members of the solanaceae family, members of the rosaceous family, members of the ericaceous family, and the like when in favorable climatic conditions for the development of the disease you can almost completely lose the crop and to avoid it, farmers will have to invest large sums of money in applying materials based on antibiotics depending on their legislation and their availability.

The use of antibiotics in agriculture, such as gentamicin, oxytetracycline, streptomycin, and kasugamycin, offer viable alternatives for the prevention and control of these exemplary pathogens, but the use of these antibiotics has been limited during recent years in Europe, Japan, Australia, New Zealand, and Brazil. Because of this, producers have very limited options to treat or prevent the bacterial diseases which, year-by-year, reduce their crops and cause large losses of their crops. Producers can only use formulations based on copper for foliar applications, which offers a limited control of the sanitary emergency they have. In these countries, where the use of antibiotics is forbidden for agricultural use, the incidence of bacterial diseases is increasing in a worrying way, and in some places, such as Italy, Spain, New Zealand, France, and others countries, the production of both vine and kiwi are going through a delicate stage due to the presence of diseases caused by bacteria that have devastated complete cultivars. In Australia, there exists a serious worry by the government and producers of a bacterial disease that has been presenting in wheat, blueberries, sugarcane, and cereals, thereby putting in check the production of these foods. The same happens in Brazil, the United States, and England, where producers of citrus crops are reporting incalculable losses resulting from a disease called the “Yellow Dragon,” which is caused by the bacterium Candidatus liberibacter also affecting China, Taiwan, India, Malaysia, Indonesia, Myanmar, the Philippines, Pakistan, Thailand, Nepal, Saudi Arabia, Afghanistan, and others.

SUMMARY

The main purpose of this disclosure is to provide a new antibacterial formulation acceptable for agricultural use. The formulation is effective to prevent, treat, and control diseases caused by bacteria and fungus in plants, while also providing for an environmentally-friendly composition, thereby permitting its authorized use in those countries that have high registry standards and those countries in which the use of antibiotics have been controlled or forbidden.

The formulation comprises tannins as active ingredient mixed with agriculturally acceptable excipients, for example, a lignin such as sodium lignosulfonate, a polycyclic aromatic hydrocarbon such as naphthalene sulfonate, polysaccharides such as starch, and siliceous sedimentary rock such as diatomaceous earth. The agriculturally acceptable formulation can be deposited in and mixed with a reasonable amount of water to be sprinkled in very thin droplets of water “to the point of dripping” via appropriate equipment to the crop that it is intended to protect, in which bacterial damage may be present and would otherwise continue to harm the plants. The agriculturally acceptable formulation thereby avoids exceeding the profitable economic thresholds for the food producer.

The present disclosure relates, in part, to a composition comprising tannins, a method of using the composition comprising tannins, and the use of the composition comprising tannins. The disclosure below provides additional detail regarding the contents of the composition and how it may be used and applied to plants.

Tannins have been used since ancient times in the tannery industry. Egyptians used the fruits of acacias for tannery purposes, and tannins are also used in wine making and medicine to naturally treat some diseases in humans. Tannins are very astringent polyphenolic compounds and have a bitter taste.

To form the agriculturally acceptable formulation, a pre-mixture of tannins may be used to which the other materials present in the agriculturally acceptable formulation may be added. An example of a pre-mixture of tannins includes a mixture that contains about 65% tannins (a mixture of about 35.5% castalagin, about 23.3% vascalagin, about 2.0% castalin, and about 5.0% vescalin), about 15% sugars, and about 15% bentonite, with the remainder being water (unless otherwise noted, this pre-mixture will be referred to as Pre-Mixture A). The contents of the pre-mixture are not particularly limited, but an exemplary pre-mixture may comprise tannins, carbohydrates, and bentonite.

One exemplary formulation includes a mixture of 5% by mass of Pre-Mixture A and 95% by mass diatomaceous earth (e.g., 50 grams of tannins per kilogram of the formulation and 950 grams of diatomaceous earth per kilogram of the formulation).

Another exemplary formulation includes a mixture of 10% by mass of Pre-Mixture A and 90% by mass diatomaceous earth (e.g., 100 grams of tannins per kilogram of the formulation and 900 grams of diatomaceous earth per kilogram of the formulation).

Another exemplary formulation includes a mixture of 20% by mass of Pre-Mixture A and 80% by mass diatomaceous earth (e.g., 200 grams of tannins per kilogram of the formulation and 800 grams of diatomaceous earth per kilogram of the formulation).

Another exemplary formulation includes a mixture of Pre-Mixture A (200 grams, 20% by mass), sodium lignosulfonate (40 grams, 4% by mass), naphthalene sulfonate (20 grams, 2% by mass), xanthan gum (5 grams, 0.50% by mass), and diatomaceous earth (735 grams, 73.50% by mass).

The agriculturally acceptable formulation of the present disclosure can be, for example, deposited in and mixed with a reasonable amount of water to be sprinkled in very thin droplets of water “to the point of dripping” via appropriate equipment to the crop that it is intended to protect, in which pathogen damage may be present and would otherwise continue to harm the plants. The amount of water that may be mixed with the agriculturally acceptable formulation may be, for example, 50 liters of water per 2 kilograms per hectare when applied by airplane; 1000 liters of water per 2 kilograms per hectare when applied to plants via a sprayer; 400-600 liters of water per 2 kilograms per hectare when used on plants such as tomatoes, peppers, onions, and the like. The amount of water used is not particularly limited, however, and any dilution may be used so long as it provides for the anti-pathogenic effects disclosed herein.

The method by which the agriculturally acceptable formulation may be administered to plants is not particularly restricted. Examples include the application of the agriculturally acceptable formulation by airplane or sprayer (such as an airblast sprayer, a manual sprayer, or a mechanical sprayer). The agriculturally acceptable formulation may also be applied by a drencher, in which the agriculturally acceptable formulation is administered to the soil. In addition, the agriculturally acceptable formulation may be applied to plants via irrigation systems. In certain instances, the agriculturally acceptable formulation may also be injected into a plant.

The agriculturally acceptable formulation may be applied to a plant, a plant's foliage, or may be applied to the soil. For example, the agriculturally acceptable formulation may be applied to the foliage, stem, canopy, trunk, roots, shoots, twigs, and/or flowers of a plant. The agriculturally acceptable formulation may also be applied to seeds and to a plant's rhizomes. The agriculturally acceptable formulation may be applied to seedlings.

If applied to a plant or a plant's foliage, the agriculturally acceptable formulation may be administered in an amount so as to provide for the bactericidal effect of the present disclosure. For example, the agriculturally acceptable formulation may be applied so as to administer the amount of tannin necessary to provide for anti-pathogenic effects of the present invention. Such amounts may be determined based on the concentration of tannins present in the agriculturally acceptable formulation. For example, an amount of 2 kilograms (diluted in an appropriate amount of water) per hectare of plants may be appropriate. The agriculturally acceptable formulation may be administered to plants in intervals of, for example, 1-21 days, preferably intervals of 2-14 days, and also preferably intervals of 3-7 days. However, the amounts and intervals are not limited thereto and may be determined based on the agriculturally acceptable formulation. The agriculturally acceptable formulation can be administered in the nursery stage, the seedling stage, the transplant stage, the vegetative stage, pre-bloom, during full-bloom, post-bloom, and during fruit set. The agriculturally acceptable formulation can also be administered during a plant's dormancy.

The agriculturally acceptable formulation of the present disclosure may be made by mixing together the materials listed above. The manner in which the materials are mixed is not particularly limiting. The agriculturally acceptable formulation may then be added to a predetermined amount of water and, if necessary, water conditioner.

The agriculturally acceptable formulation is a bactericidal and fungicidal formulation that can be used in a wide variety of plants and plant species that have great economic importance. These include, but are not limited to, vegetables crops such as artichoke, asparagus, beet, beetroot, bell pepper, broccoli, brussels sprout, cabbage, carrot, cauliflower, celery, sweet corn, cucumber, eggplant, beans, green bean, onion, green onion, leek, lettuce, pea, pepper, potato, pumpkin, radish, spring onion, squash, sweet potato, tomato, zucchini, and mushrooms; as well as cereal crops such as wheat, oats, corn, rice, barley, sorghum, triticale, quinoa, and the like; as well as fruit crops such as avocado, apple, pears, peaches, plum, banana, prune, citrus, lemons, oranges, pomegranate, papaya, mango, lychee, rambutan, strawberry, cranberry, blackberry, raspberry; as well as other crops such as nuts, pastures, sugar cane, and the like.

The agriculturally acceptable formulation has also shown benefits in the treatment of nurseries and seedbeds, as well as in ornamental plants, such as flowers that include chrysanthemums, daisies, roses, begonias, gladiolas, geraniums, gardenias, and carnations. The agriculturally acceptable formulation is also beneficial to protect shade trees, forest trees, and annual and bi-annual crops from bacterial diseases.

Without wishing to be bound by theory, it is believed that tannins affect bacteria by actively modifying the environment where they grow, multiply and feed, developing a condition of hyper change.

Tannins react with the bacterial cell membrane and cause the death of the bacterial cell.

Bacteria are divided mainly into two groups (gram negative and gram positive), whose difference lies in the composition of their cell wall. Gram-negative bacteria have a single layer of peptidoglycan and a surface membrane composed of lipoproteins and glycoproteins, while gram-positive bacteria do not have a surface membrane and contain many layers of peptidoglycan, so their thickness is considerable.

The function of the cell wall is to shape and protect the interior of the cell from changes in pressure or exchange of extracellular fluids. This determines the survival of the cell. As mentioned above, the cell wall consists mainly of proteins in their different forms (phosphoproteins, glycoproteins, lipoproteins, and the like). Gram-negative bacteria contain a greater amount of proteins, while gram-positive bacteria on the surface contain teichoic acid, which is formed by glycerol polymers and a few proteins.

For this reason, an organic agriculturally acceptable formulation containing ellagic tannins mainly damages gram-negative bacteria and fungus, and also damages gram-positive bacteria that may be susceptible to the product.

Upon contact of the tannins with the cell wall, the cell wall is lysed and destroyed, and cell survival is compromised due to osmotic pressure and damage by external agents.

EXAMPLES

Some of the tests discussed herein were carried out in a laboratory, and objectively show the bactericidal effect of the presently disclosed agriculturally acceptable formula based on tannins in different concentrations against five genera of bacteria which are the most important that attack plants of economic importance.

For the relevant Examples, phytopathogenic strains, such as Xanthomonas sp., Clavibacter sp., Erwinia sp., Pseudomonas sp., and Ralstonia sp., were isolated from different fruits and vegetable crops. A mixture for agricultural use was developed in accordance with the following descriptions.

The sensitivity of bacteria to a given formulation was evaluated in petri dishes using a poisoned food method, using agar culture media mixed with the proper amount of the formulation. The poisoned food method is commonly used to evaluate antifungal effects against molds, and the method was modified to test bacteria instead of mold. In the method, the relevant formulation was incorporated into molten agar at a desired final concentration and mixed well. Then, the resulting medium was poured into petri dishes. After overnight pre-incubation, the petri dishes containing the medium were inoculated with the relevant bacteria. After further incubation under suitable conditions for the bacterial strain tested, the positive or negative growth in the control and sample plates was measured. Thus, in brief, this methodology used the agar as a vehicle for the product dose, and after solidification, a very high concentration of bacterial suspension, was inoculated, while leaving a control petri dish inoculated with the same bacterial suspension containing only agar without the formulation.

The respective formulation was mixed with agar to prepare the appropriate concentration for each example. For example, to form a 0.1 grams per liter formulation, 0.1 grams of the formulation was added to 1 liter of agar. It is understood that the results using agar will correspond to the results that would be obtained if using water instead of agar. Thus, the results obtained using agar are understood to correspond to results that would be obtained if water were used as a medium.

Results were measured after 96 hours. The number of bacterial colonies was counted by a technique that is based on counting the “colony forming units,” or CFU, present in a gram or milliliter of the sample. It was considered that each colony that develops in the culture medium of choice after a certain incubation time at the appropriate temperature comes from a microorganism, or an aggregate of them, of the sample under study. It was also considered that the microorganism or microorganisms were capable of forming the colony, i.e., that the microorganism(s) is a CFU. To reliably count the colonies, the necessary decimal dilutions of a sample were made before putting it in the culture medium. The most common procedure for the enumeration of bacteria is the viable plate count. In this method, serial dilutions of a sample containing viable microorganisms were plated onto a suitable growth medium. The suspension was either spread onto the surface of agar plates (spread plate method), or was mixed with molten agar, poured into plates, and allowed to solidify (pour plate method). The plates were then incubated under conditions that permitted microbial reproduction so that colonies that could be seen without the aid of a microscope were formed. It was assumed that each bacterial colony arises from an individual cell that has undergone cell division. Therefore, by counting the number of colonies and accounting for the dilution factor, the number of bacteria in the original sample was determined.

For the noted Examples, the results were positive, as discussed below, and showed a bactericide effect in some instances from a dose of 1 or 2 grams per liter, where no bacterial growth was shown, as compared to a control that contained the bacterial suspension without any formulation.

As described below, some mixtures were assigned codes A5, B15, A, and +20. A5 described a composition that included Pre-Mixture A (21.98% by mass), gentamicin sulphate (8.08% by mass), sodium lignosulfonate (4% by mass), naphthalene sulfonate (2% by mass), xanthan gum (0.50% by mass), and diatomaceous earth (63.44% by mass). B15 described a composition that included Pre-Mixture A (21.98% by mass), oxytetracycline (15.69% by mass), sodium lignosulfonate (4% by mass), naphthalene sulfonate (2% by mass), xanthan gum (0.50% by mass), and diatomaceous earth (55.83% by mass). Composition A was a composition containing 20% by mass of Pre-Mixture A, 4% by mass of sodium lignosulfonate, 2% by mass of naphthalene sulfonate, 0.50% by mass fo xanthan gum, and 73.5% by mass of diatomaceous earth. “+20” described a composition that included Pre-Mixture A (21.98% by mass), copper oxychloride (20% by mass), sodium lignosulfonate (4% by mass), naphthalene sulfonate (2% by mass), xanthan gum (0.50% by mass), and diatomaceous earth (51.52% by mass).

In each formulation for the Examples herein, the diatomaceous earth (when used) was sterilized at 200° C. for 2 hours prior to its addition to the formulation.

Premixture

Where indicated, Pre-Mixture A was used. As noted above, Pre-Mixture A contained about 65% tannins (a mixture of about 35.5% castalagin, about 23.3% vascalagin, about 2.0% castalin, and about 5.0% vescalin), about 15% sugars, and about 15% bentonite, with the remainder being water.

Example 1A

The effectiveness of the formulation on Clavibacter sp. was tested using different concentrations of the premixture of tannins in the formulations (e.g., 5%, 10%, and 20%) and by applying different concentrations of each formulation.

The formulation containing 5% of the premixture of tannins included a mixture of 5% by mass of Pre-Mixture A and 95% by mass diatomaceous earth (50 grams of tannins per kilogram of the formulation and 950 grams of diatomaceous earth per kilogram of the formulation).

The formulation containing 10% of the premixture of tannins included a mixture of 10% by mass of Pre-Mixture A and 90% by mass diatomaceous earth (100 grams of tannins per kilogram of the formulation and 900 grams of diatomaceous earth per kilogram of the formulation).

The formulation containing 20% of the premixture of tannins that included a mixture of 20% by mass of Pre-Mixture A and 80% by mass diatomaceous earth (200 grams of tannins per kilogram of the formulation and 800 grams of diatomaceous earth per kilogram of the formulation).

FIGS. 1(a)-(c) show the results when the premixture of tannins was present in the formulation at an amount of 5% by mass. The upper left hand petri dish in each of FIGS. 1(a)-(c) are the control petri dishes, in which no formulation was applied. FIG. 1(a) shows results when the formulation containing 5% by mass of the premixture of tannins was administered in a solution containing 0.1 g/L, 0.2 g/L, and 0.3 g/L of the formulation. FIG. 1(b) shows results when the formulation containing 5% by mass of the premixture of tannins was administered in a solution containing 0.4 g/L, 0.5 g/L, and 1.0 g/L of the formulation. FIG. 1(c) shows results when the formulation containing 5% by mass of the premixture of tannins was administered in a solution containing 2 g/L, 4 g/L, and 6 g/L of the formulation.

As can be seen from FIGS. 1(a)-(c), effective doses of the 5% formulation in this test were deemed to be 4 g/L and 6 g/L, which were the concentrations at which the Clavibacter sp. grew at a much lower rate than the control. In the 4 g/L and 6 g/L concentrations, the Clavibacter sp. was not visibly present, and hence did not grow in the agar.

FIGS. 2(a)-(c) show the results when the tannins were present in the formulation at an amount of 10% by mass of the premixture. The upper left hand petri dish in each of FIGS. 2(a)-(c) are the control petri dishes, in which no formulation was applied.

As can be seen from FIGS. 3(a)-(c), effective doses of the 20% formulation in this test were deemed to be 0.5 g/L, 1 g/L, 2 g/L, 4 g/L, and 6 g/L, which were the concentrations at which the Clavibacter sp. grew at a much lower rate than the control. In the 0.5 g/L, 1 g/L, 2 g/L, 4 g/L, and 6 g/L concentrations, the Clavibacter sp. was not visibly present, and hence did not grow in the agar.

Example 10

An agriculturally acceptable formulation was created having a composition of a mixture of Pre-Mixture A (200 grams, 20% by mass), sodium lignosulfonate (40 grams, 4% by mass), naphthalene sulfonate (20 grams, 2% by mass), xanthan gum (5 grams, 0.50% by mass), and diatomaceous earth (735 grams, 73.50% by mass).

The agriculturally acceptable formulation at a concentration of 2000 g/1000 L of solution was tested, alongside an untreated control, to which no type of antibiotic was applied during the test, in an apple orchard that had a history of strong disease (Erwinia amylovora) pressure. The orchard contained and was surrounded by conditions conducive to the development of the disease such as: high moisture content in the upper part of the subsoil, adjacent orchards that had the Gala apple variety with a high contamination in previous years, and a manifestation of zooglea pre-sprouting in its own sectors, which led to the decision to plant new trees in the orchard. The cultivation that was tested was an apple tree of the variety Golden Smoothie.

In this test, five applications were made on 220 trees, using 250 liters of water to cover ¼ Ha (hectare) with an airblast sprayer. Trees in the treatment area were sprayed using an airblast sprayer until water run off covering 4 rows. Sprays were timed to coincide with the tree fruit bloom and petal fall. The test area was sprayed once every 6-9 days during bloom season. Thus, the pre-bloom period was covered as well as the flowering period.

The applications were made on the following days at the following dosages:

TABLE 34 Date Dosage Day 1 500 g/Ha Day 9 1 kg/Ha Day 15 1 kg/Ha Day 24 1 kg/Ha Day 33 1 kg/Ha

An evaluation was made on Day 38, a date in which any infection caused by the disease during the bloom period (blossom blight) would be visible.

The experiment was arranged in a paired T-test. Data were analyzed through a T-Test analysis using the statistical package R (R Core Team (2016). R: A language and environment for statistical computing. R Foundation for Statistical Computing, Vienna, Austria. URL https://www.R-project.org/). As noted above, one evaluation was made 5 days after the last spray. Mean data of the number of blossom infection per tree was collected. Data collected from the orchard showed that the effect of the new antibacterial formulation based on tannins was significant (P<0.05). Compared with the untreated control, the new antibacterial formulation based on tannins controlled the blossom blight infection.

FIGS. 50(a) and (b) show examples of blossom blight that were measured during this test. Table 35 shows the statistics measured in this test. FIG. 51 is a graphical representation of the data in Table 35.

The Shapiro-Wilk normality test value is W=0.91053 with a p-value of 0.3578. The t value of this data was −5.1178, with a df value of 6 and a p-value of 0.002183.

This experiment showed that the new antibacterial formulation based on tannins showed an effect in decreasing the amount of infected blossom shoots against the control (which was not exposed to the formulation). This is important because each infected bud (blossom blight) is a point of production that is lost during the following 4 years. That is, the productive wood of that floral bud, apart from generating zero production in year of its infection, loses its productive value, generating fruit wood compensation costs and latent risks of future infections.

Example 11

In this experiment, a shoot blights infection (Erwinia amylovora) after flowering was present in a Gala apple variety.

In this particular batch, a hail event occurred, and due to the wounds from the hail, an initial shoot blight outbreak occurred. Pruning of the infected initial shoots occurred in both the treatment lot and the control lot, after which the new antibacterial formulation based on tannins was applied to the treatment lot.

Four applications of the new antibacterial formulation based on tannins were scheduled so as to cover the season of high relative humidity due to rain. The applications were made on Day 1, Day 6, Day 11, and Day 18; at a dose of 2.0 kg/Ha.

The applications of the new antibacterial formulation based on tannins were made with an airblast sprayer machine using 1000 liters of solution per Ha, covering 9 rows of 47 trees each. Both in the treated area and in the control, a useful plot of 5 rows was measured. Evaluations were made counting the number of shoot blights per tree on Day 15 and Day 28.

The formulation that was applied in this Example was the formulation described in Example 10 at a concentration of 2000 g of formulation per 1000 liters of water. Trees in the treatment area were sprayed using an airblast sprayer until water run off. In this test, sprays were timed every 5 days post-petal fall to cover further shoot infections, known as “shoot blights.” The test area was sprayed once every 5 days for three cycles, and one time 7 days after the third application. The experiment was arranged in a paired T-test. Data were analyzed through a T-Test analysis using the statistical package R (R Core Team (2016). R: A language and environment for statistical computing. R Foundation for Statistical Computing, Vienna, Austria. URL https://www.R-project.org/). A first evaluation was made 4 days after the third spray. Data of the number of shoot blights per row was collected. Data collected from this test in the first evaluation showed that the effect of the invention was significant (P<0.05). Compared with the untreated control, the new antibacterial formulation based on tannins controlled the post-petal fall infection known as shoot blights (see Table 36). FIG. 52 is a graphical representation of the data in Table 3.

The Shapiro-Wilk normality test value was W=0.93245, with a p-value of 0.4724. The mean in the treated group was 80.6, whereas the mean in the untreated group was 232.6, thus exemplifying the antibacterial effect of this composition. The t value of this data was −3.2116, with a df value of 8 and a p-value of 0.0124.

A second evaluation was made 10 days after the fourth spray. Field data were transformed (log [y]) to reduce variance. Data collected from this test in the second evaluation showed that the effect of the new antibacterial formulation based on tannins was significant (P<0.05). Compared with the untreated control, the new antibacterial formulation based on tannins controlled the post-petal fall infection known as shoot blights (see Table 4). FIG. 53 is a graphical representation of the data in Table 37.

The Shapiro-Wilk value of this transformed data was W=0.8547, with a p-value of 0.06605. The mean in the treated group was 2.037679, whereas the mean in the untreated group was 2.761950, thereby illustrating the antibacterial effect of this composition. The t value of this data was −5.2241, with a df of 8 and a p-value of 0.0007986.

Linear prediction maps (Kriging) were made after Day 28 and are shown in FIGS. 54(a) and (b). FIG. 54(a) shows the number of shoot blights in the area treated with the new antibacterial formulation based on tannins. FIG. 54(b) shows the control area, which was adjacent to the test area. The images simulate an aerial view of the crop, where with each of the values of shoot blight, an interpolation was made between the points (in this Example, apple trees). The scale on the right indicates the colors assigned by number of infected shoots (shoot blights), the white colors being the indicator of the greatest number of infected spots in the area.

This Example shows that the use of the new antibacterial formulation based on tannins in the cultivation of Gala apple trees at a rate of 2 kg/ha provides for a significant improvement against an untreated control in terms of the mean number of infected shoots per row (shoot blights).

Example 12

An agriculturally acceptable formulation was created having the composition of Example 10—a mixture of Pre-Mixture A (200 grams, 20% by mass), sodium lignosulfonate (40 grams, 4% by mass), naphthalene sulfonate (20 grams, 2% by mass), xanthan gum (5 grams, 0.50% by mass), and diatomaceous earth (735 grams, 73.50% by mass). A solution of the agriculturally acceptable formulation in water was created, having a concentration of 7.5 grams of the agriculturally acceptable formulation per liter. 37.5 g of the solution was weighed and added to agar, using the poisoned food technique of Example 1A.

The pathogenic fungus Alternaria sp. was added to the agar and was incubated at 28° C. for 120 hours. This was repeated in four petri dishes. Following incubation, an evaluation was made in which the measurements of the fungal growth diameters in the agriculturally acceptable formulation-containing agar was compared with the diameter of four controls which contained the agriculturally acceptable formulation but did not contain the pathogenic fungus. A Percentage of Inhibition was calculated from each sample using the following formula, and the mean of the four repetitions was taken as the inhibition percentage for the Example: Percentage of Inhibition=((Radial growth of the control−Radial growth of the pathogen)/Radial growth of the control))*100
